🔍 Key Concepts

• ARQ in maritime digital/NBDP communications (what kind of link and how many stations are involved) • Difference between FEC and SFEC (who receives the message and whether there is a return channel) • Concept of one-way vs. two-way communication and single station vs. all stations addressing

💭 Think About

• Ask yourself: In ARQ mode, is the sender expecting acknowledgements from the receiver? What does that imply about one-way or two-way communication? • For FEC, think: does the sender wait for any reply, or do they just transmit for anyone to copy? How many stations can receive that message? • For SFEC, how is it different from normal FEC? Does the message go out to everyone or is it directed to a specific address?

✅ Before You Answer

• Verify which mode (ARQ, FEC, SFEC) uses automatic repeat requests/acknowledgements, indicating two-way communication. • Confirm whether FEC transmissions are generally intended for all stations in range to receive without replying. • Confirm whether SFEC (Selective FEC) is directed to one specific station rather than all stations.
